I recently went to a Cylinder head machining shop in town which apperently is a reputable place. I asked them what specs they machine the heads to?
(because from reading on here they are NOT supposed to take off more than .008")

Well their answer to me was, "IT Doesn't matter because we re-seat the valves after milling."
Im no genius, but I think that something is wrong...
Could the techs please chime in and help me understand this?

Cutting the valve seats deeper will only make the problem worse. Find a better shop to do the work-one that understands and works on the powerstroke, and knows what type of finish is required for MLS gaskets!

Recessing the valves can save an otherwise dead head but there is still a limit to what is reasonable. Taking .0012 off and recessing the valves .006 isn't too radical. Taking .020 or more is a different thing altogether.

Thank you very much!
That all makes sense now.
These guys apparently are doing most of the head work in town and they said that they have had no problems with their work.
